Calculate the mass of limestone required to produce 112 kg of quicklime by burning it.

Text Solution

Verified by Experts

`underset("1 mole")(CaCO_(3))overset(Delta)tounderset("1 mole")(CaO+CO_(2))`
=40+ 12+48 =40+ 16
= 100g =56g
`therefore` 56 kg of CaO is obtained from limestone= 100kg
112 kg of CaO is obtained from lime stone
`=(100)/56xx112=200` kg
